BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stator for a magnet type generator used in a two-wheeled vehicle or the like.

[0002]

2. Description of the Related Art Magnet type generators used in two-wheeled vehicles are
It is mounted on the engine and has excellent earthquake resistance, and it is required to be compact. The stator 9 of this magnet type generator (3 phase) is shown in FIG.
As shown in FIG. 3, a plurality (3n) of magnetic poles 90 are provided and arranged in a rotationally symmetrical manner. The magnetic pole 90 is obtained by winding an armature coil 92 around a core 91 formed by stacking iron plates, and lead wires 93 of each phase (three) are connected to lead wires 94.

That is, the three lead wires 93 are twisted with each other so as not to float, and are raised from the magnetic pole 90. After removing the coating, the lead wires 94 are soldered to the sleeve 951.

[Problems to be Solved] However, the stator of the conventional magnet type generator has the following problems. The first problem is that the workability of assembling is poor and the connection parts are likely to be uneven. In particular, if the wire diameter of the winding becomes large, it becomes difficult to twist and connect the lead wire 93 by hand.
Further, since the work is done manually, the finish is not uniform, the length of the lead wire 94 is varied, and the insulation strength between the core 91 or the mounting member 971 and the connecting portion is not uniform.

The second problem is that there are many restrictions on saving space. At the connection portion, the conductors of the lead wire 93 and the lead wire 94 are directly soldered to each other, so that the connection portion of the lead wire 93 and the lead wire 94 must be arranged in parallel, and the connection portion to be soldered must be a certain amount or more. The length is required, and there are restrictions on space saving and freedom of arrangement.

A third problem is that since the wire connecting portion is not directly fixed by a clamp or the like, vibration is easily transmitted, and the seismic resistance is slightly deteriorated. In view of such conventional problems, the present invention is to provide a stator of a magnet type generator which has few restrictions on installation space, is excellent in connection reliability, and has good earthquake resistance and workability. .

Actions and Effects The stator of the magnet type generator according to the present invention is provided with the above-mentioned relay connection member, which allows the following actions and effects to be obtained. The relay connection member is attached to the locking part of the core,
It is installed in a fixed position. The lead wire and the lead wire are connected to the terminal plate of the relay connection member, and the lead wire and the lead wire are not directly connected as in the conventional case.

Therefore, the work of connecting the lead wires and the work of connecting the lead wires are much easier than in the prior art, the connection quality is good, and the position of the connection portion is constant. That is,
Since the lead wire can be connected to the internal terminal after being locked to the relay connection member by the locking part of the housing,
Wiring workability is good and wiring quality is good. In addition, the position of the wire connection is constant and the insulation strength is also uniform. Then, the work of twisting the lead wires together becomes unnecessary.

On the other hand, since the lead wire is fixed to the holding portion of the external terminal portion and then fixed to the connecting portion, the workability of connection is good and the connection quality is good. In addition, the position of the wire connection is constant and the insulation strength is uniform. Since the ends of the lead wires are molded integrally with the housing, they are stably held in the housing.

Further, since the connecting portion of the lead wire and the lead wire is held by the relay connecting member fixed to the core, it does not float and is excellent in earthquake resistance. Also, since the lead wire is connected to the terminal board and not connected to the lead wire as in the conventional case, there are less restrictions on the direction in which the lead wire is inserted into the stator, and the space occupied by the wire connection part is also small. There are less restrictions on.

This is because, when the wire members are connected to each other by soldering or the like, the length of the joint is longer than that of the connection between the wire member and the terminal plate, and the lead wire entry direction is restricted.
This is because the occupied space becomes large and the installation direction is restricted. As described above, according to the present invention, it is possible to provide a stator for a magnet-type generator that has few restrictions on installation space, has excellent connection reliability, and has good earthquake resistance and workability.
